SERVICE · ERP INTEGRATION

ERP integration that keeps orders, stock and invoices in step.

Seamwire builds ERP integration for mid-size companies. We connect your ERP (SAP Business One, Dynamics 365 Business Central, NetSuite, Odoo, Sage, Tally and others) to the CRM, online store, warehouse, accounting package and spreadsheets around it, so an order, a stock movement or an invoice is entered once and matches in every system. We agree which system owns which data, build each connection with logs and alerts, and hand you everything we built.

SIGNS YOU NEED THIS

  1. 01Online orders are retyped into the ERP before anyone can ship them.
  2. 02The stock figure on your website is not the stock figure in the ERP.
  3. 03Sales win a deal in the CRM, then someone keys it in again as an order.
  4. 04Finance reconciles ERP exports against the store and the bank by hand.
  5. 05A native connector was installed, but it skips the fields your process depends on.
  6. 06Nobody can say which system holds the right price, address or stock level.

HOW IT WORKS

  1. 01

    A 10-day first step

    One process or page, mapped with the people who do the work and shown working. You leave with a business case and a dated plan, and keep everything it produced.

  2. 02

    Build in short, visible steps

    Working software every week or two on a staging site you can click, with weekly written notes on what moved and what we need from you.

  3. 03

    Launch and hand over

    Released carefully, with monitoring switched on, then a handover pack: code, docs, runbooks and a session with your team.

  4. 04

    Look after it

    Support, monitoring and improvements on terms agreed in writing before we start, with a named team who knows the work.

QUESTIONS BUYERS ASK

What is ERP integration?
ERP integration means connecting your ERP to the other systems the business runs on, such as the CRM, online store, warehouse, accounting and bank, so data moves between them automatically. In practice it is a set of agreed flows (orders in, stock and prices out, invoices across), each with a defined owner, field mapping, error handling and a log. Done well, nobody retypes data and every screen shows the same figure.
Native connector, middleware or custom API: which method is right?
A native connector, built by the ERP or app vendor, is the quickest route when it covers your process and your fields. Middleware or an iPaaS platform such as Celigo or Boomi suits companies linking several cloud systems who want visual mapping and monitoring for a subscription. A custom API integration gives full control over logic, volumes and edge cases, and you own it outright. Combining them is common; we recommend the simplest one that genuinely fits.
Which system should own which data?
Each piece of data gets one owner: the system where it is created and corrected. Usually the ERP owns items, stock, prices and invoices, the CRM owns leads, contacts and the pipeline, and the online store owns the basket and checkout. Other systems read from the owner or send changes back to it. We agree this record by record in the first step, because most sync problems start where two systems both think they are in charge.
Can you integrate Shopify with our ERP?
Yes. Shopify orders, customers and payments flow into the ERP as sales orders, and stock levels, prices, fulfilment and tracking flow back to the store. We handle the awkward parts on purpose: variants and bundles, partial shipments, refunds and returns, discounts, several warehouses and several currencies. If an existing Shopify app connector already covers your setup, we will say so and configure it rather than build.
What if our ERP has no API?
Older and on-premise ERPs often lack a modern API, but there is nearly always a way in: a careful database connection, the ERP's own import and export tools on a schedule, EDI, files over SFTP or, as a last resort, screen automation. We choose the most reliable route, put a small API layer in front of it so other systems get a clean interface, and tell you plainly what its limits are.
How long does a first ERP connection take?
Every project starts with the 10-day first step. In it we map one flow, for example web orders into the ERP, with the people who run it, agree data ownership and field mappings, and show that flow working against a test copy of your systems. You leave with a business case and a dated plan for the rest, so you see the full timeline before you commit to it.
Do we need to replace our ERP first?
Usually not. Much of the pain blamed on an ERP comes from the gaps between it and everything else, and closing those gaps carries far less risk than a migration. If your ERP genuinely cannot support the business, we will say so with the reasons, and the integration work, mappings and documentation carry over to whatever replaces it.
